Abstract: 258,473. Burguet, A. Zund-. Feb. 2, 1926. Massage.-Apparatus for pneumatic massage is arranged to yield either suction, pulsating pressure, or a combination of the two; special forms of applicator are also described. The pump is of the reciprocating type and is furnished with a passage 16 communicating with the applicator and a passage 20 communicating with the atmosphere. These passages are controlled by spring blades 14, 18 acting as valves, so that when the blades are free the pump acts as a suction pump. Bv means of a screw 10 the blade 14 can be lifted off its seating to a greater or less extent, the motion of the blade 18 being controlled to a corresponding degree by the head of the screw. The applicator may be a narrow-ended tube or a cone of rubber or the like. In the latter case a rotatable piece 44, Fig. 9, may be supported in it by spring arms 45. Fig. 8 shows a device to be inserted in the rectum for massaging the prostate. It consists of a closed chamber 34 of rubber &c. into which passes a sliding tube 37 connected with the pump.

Abstract: 1400461 Disposal of toilet waste SEATRAX Ltd 22 March 1973 [21 Jan 1972] 3093/72 Heading E1C Raw sewage, e.g. from a marine toilet 1, is delivered by a discharge pump 2 to a holding and treating unit 4 comprising chambers 9-12 in the first of which, chamber 9, is a dispersing means, e.g. a rotary chopper 23 formed by propeller blades secured to a shaft 24 driven by electric motor 21, while chambers 10, 11 and 12 are respectively first and second treating chambers and a standing chamber, there being included a control arrangement whereby the dispersing means is operable intermittently, each time in response to a rise in pressure caused by the introduction of new influent to the chamber 9. The arrangement comprises an air bell 18 in which air is trapped whenever the level in chamber 9 rises above its bottom edge, and a pressuresensitive switch and relay arrangement 19, 20 operative to energise the motor 21 whenever the pressure in the treating unit rises to a predetermined value. Pressure builds up in the treating unit as a result of fluid flow restrictions consisting of weir 26, orifices 33, 34, 14, and a spring-loaded valve 16 normally closing an opening 15. When the predetermined value of pressure is reached, liquid in a venting arrangement 13 rises to a level L'. The further rise in pressure caused by starting of the motor 21 causes valve 16 to open and the liquid with dispersed sewage to flow over plates 27, 27' past the lower ends of containers 28, 28' containing treating chemical and through openings 32, 32' to respective chambers 10, 11, while the treated sewage passes to container 12 which in turn discharges via pipe 5 either overboard or, via a changeover valve 7 and a further pipe 8, to a storage tank. The toilet is flushed either with sea water or with treated liquid recirculated by a further pipe 37 and a chamber 36 which may include further treatment apparatus or may take over the functions of the containers 28, 28', which are then omitted. An arrangement of valves for enabling the unit 4 and the storage tank (36) to be flushed with sea water (Figs. 2a-2d, not shown) is also described, as is also a modification (Fig. 3, not shown) of the unit 4.
